FRANKLIN A. PETTIBONE, 0F CONEWANGO VALLEY, NEW YORK.

TIRE-TIGHTENEB.

Application filed February 24, 1915.

To all whom it may concern Be it known that I, FRANKLIN A. Pnrrr- BONE, a citizen of the United States, res1ding at Conewango Valley, 1n the county of Cattaraugus and State of New York, have invented certain new and useful Improvements in Tire-Tighteners, of which the fol lowing is a specification, reference being had to the accompanying drawlngs.

This invention relates to certain improvements in tire tighteners; and an object of the invention is to provide a device of thls general character having novel and 1mproved means whereby a tire may be contracted or expanded with convenlence and facility in accordance with the necessltles of practice.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my proved tire tightener whereby certaln 1mportant advantages are attained andthe device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claim.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a longitudinal sectional View illustrating a tire tightener constructed in accordance with an embodiment of my invention; Fig. 2 is a top plan View of the device as disclosed in Fig. 1; Fig. 3 is a sectional view taken substantially on the line 3-8 of Fig. 1; and Fig. 4 is a sectional view taken substantially on the line l4 of Fig. 1.

As disclosed in the accompanying drawings, 1 denotes the folly of a wheel having a portion thereof separated and between the extremities of the felly are adapted to be positioned the members 2 and 3 comprised in my improved tightener and which when in applied position are adapted to be disposed in continuity relative to the tire T. As herein embodied, the adjacent extremities of the members 2 and 8 are adapted to abut and the peripheral portion of the member 2 at its normally free end is provided with the recess 4t adapted to receive the tongue or extension 5 carried by the peripheral por- Specification of Letters Patent.

tion of the member 3 at the transverse center thereof. The adjacent extremities of the members 2 and 8 are provided with the longitudinally disposed openings 6 adapted to register and through which is directed the headed member 7, the blank 10 whereof being threaded and being disposed across the transversely arranged recess produced in the member 2 at a predetermined point re: mote from the free or outer extremity of the member and intersecting the opening 6.

The inner extremity 8 of the opening 6 disposed through the member 3 is angular in cross section at its rear portion while the shank is of corresponding cross section whereby it will be perceived that the headed member is maintained against axial rotation.

Positioned within the recess 9 is a nut or bur 11 in threaded engagement with the shank 10 whereby it will be perceived that the folly may be permitted to expand or contract upon suitable axial rotation being imparted to the nut or bur 11.

When the occasion requires that the adjacent extremities of the members 2 and 3 be separated, I find it of advantage to interpose between said separated extremities the washers or filler members 12, herein disclosed as of a configuration substantially identical to the configuration of the adjacent ends of the members 2 and 8 and provided with a central opening through which the shank 10 projects and having in communication therewith a radial slot 14, the opposed free extremities whereof being in wardly beveled and adapted to engage the opposite marginal portions of the tongue or extension 4. It will be readily understood that upon the insertion or removal of a washer that the nut or bur 11 is suitably rotated to result in firmly securing the adjacent extremities of the members 2 and 3.

From the foregoing description, it is thought to be obvious that a tire tightener constructed in accordance with my invention is of an extremely simple and compara tively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it Will also be obvious that my invention is susceptible of some change and modification Without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise ari no rangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

In combination, a split tire, the peripheral portion of one extremity of the tire'being provided with .a recess, an extension projecting from the peripheral portion of the adjacent extremity of thetireadaptedtofbe received Within the recess, said extension being of a Widthless. thanithe Widthofi the tire "and positioned at substantially the transverse center of; the tire clampingameans coacting with the extremities of :the tire, and a filler Washer adapted to be inserted between theadjacen't extremities o-fitheztire, said :Washer being provided -=With a radial .ingincommunication With the bore of the Washer, the beveled edges of the slot radiating from the axial center of the bore of the Washer, said beveled edges being arranged ZEOI'JCOHtfICttWlth IEhB longitudinal edges of the extension.
